Description

Safety Input Profile

6KΩ, 12V DC open circuit, 4V DC run

The Safedge controllers are designed to operate with the Safedge

profiles. The controller continuously monitors the profile for

actuation and generates an output signal when the profile is

depressed.

Profile

Monitoring Circuit

9KΩ

1KΩ

The Safedge controller provides a low voltage to the profile. When

the profile is pressed, the controller detects a change in resistance

and turns off its output relays. When pressure is released from the

profile, the output relays of the controller return to an on state. The

controller has redundant voltage free positively-guided output relays

which can be used to interface with a machine control system.

The ‘251’ controller comes capable of operating at 24V AC/DC, or

120/230V AC from separate terminals. An internal switch changes

the operating voltage from 120V AC to 230V AC. The ‘252’

controller operates at 24V AC/DC.

An auxiliary output relay is available to provide a signal about the

controller’s status. Three LEDs indicate whether the controller is in

RUN, STOP or OPEN condition. The controller operates in manual

or automatic reset mode.
